Background

Immunoglobulin-like domain containing receptor 1, or ILDR1, is a single pass Type I membrane protein that belongs to the immunoglobulin superfamily. Human ILDR1 contains a signal peptide (aa 1-23), an Ig-like V-type extracellular domain (aa 24-167), a helical transmembrane domain amino acids (aa168-188), and a cytoplasmic domain (aa 189-546) that contains a cysteine rich region and an arginine rich region (1). The extracellular domain of human ILDR1 shares a 96.5% homology with mouse and rat respectively. ILDR1 is mainly expressed in the prostate, with lower levels also found in testis, pancreas, heart and liver (1). ILDR1 has also been found expressed by intestinal cholecystokinin (CCK)-producing cells (2). ILDR1 has three splice variants. Two of those are expressed on the cell surface, while one is expressed in the cytoplasm, except when co-expressed with one of the other two splice variants. The cytoplasmic variant is the shortest transcript and is not found in healthy tissue, but only in lymphoma samples (1). It is suggested that ILDR1 plays a role in regulating intestinal hormone levels by stimulating release of CCK in response to fatty acids (2). Loss of function of ILDR1 is associated with Autosomal-Recessive Hearing Impairment (3). Our data shows that ILDR1 binds to human immunoglobulin-like domain containing receptor 2 (ILDR2).
